Hi ! After a clean build and install, a manifest.ttl appears to be missed. Here's what I get : $ lv2ls | fgrep dete Error opening file /usr/local/lib/lv2/deteriorate.lv2/manifest.ttl (No such file or directory) lilv_world_load_bundle(): error: Error reading file:///usr/local/lib/lv2/deteriorate.lv2/manifest.ttl http://github.com/blablack/deteriorate-lv2/downsampler_mono http://github.com/blablack/deteriorate-lv2/downsampler_stereo http://github.com/blablack/deteriorate-lv2/granulator_mono http://github.com/blablack/deteriorate-lv2/granulator_stereo $ jalv.gtk3 http://github.com/blablack/deteriorate-lv2/granulator_mon Error opening file /usr/local/lib/lv2/deteriorate.lv2/manifest.ttl (No such file or directory) lilv_world_load_bundle(): error: Error reading file:///usr/local/lib/lv2/deteriorate.lv2/manifest.ttl Plugin: http://github.com/blablack/deteriorate-lv2/granulator_mon Failed to find plugin I can't find no manifest.ttl in the source tree, below /usr/local/lib/lv2 neither.
